While current-mode control (CMC) remains the much preferred PWM scheme for switchmode power supplies, its advantages aren't automatic. Indeed, ensuring stability in a switchmode supply involves such ...

For the PDF version of this article, which includes equations, click here. Peak current control has long been a popular PWM method in switching power supplies [1] and has the equally well-known ...

Pulse-width-modulation (PWM) duty cycles above 50% require a compensating ramp — called slope-compensation — to avoid instability. With traditional slope-compensation solutions, it is difficult for ...

(Part 1 of this article provides an overview of basic current-mode control (CMC) circuits and demonstrates the need for slope compensation). Let's assume a typical application where V out and L are ...
